I will take the terrible 2's over this...

Whoever said terrible twos were the worst didn't have the Sassy Sevens yet! I have had it! We were doing good for about 2 weeks and then all of the sudden this weekend hit and it hit hard! Saturday morning I had a meeting for work and we planned on going to Sioux City after that. Abby woke up a little after 6 which is way too early for her on the weekends! But I thought, or hoped, she would relax until I got back from my meeting and would be in a good mood to go to Sioux City. Boy was I wrong! It was attitude after attitude. Her manners were horrible and no matter what we said she did the opposite. We finally got home about 8:30 and she went to bed after I told her she was not to get out of bed before 7:30am. She gets up again right after 6. Again all day she was a bear! We made her take rest time from 1-2 hoping that would help. She laid on her bed for an hour reading and was ok for about an hour after. Then the attitude started back up. I can't even tell you how many times today I have heard how mean I am. This is ridiculous! What happened to my nice sweet little girl? I am sure a lot of this has to do with her lack of sleep but what do I do to keep her in bed later on the weekends?
Tommorrow night we have parent teacher conferences. I am sure I will hear what a sweet child she is. Does a different kid come home from school? Is my child wandering the halls at night while I get this sassy seven year old instead? I have no idea what to do anymore! I am at my wits end!
